2 Claims.

This invention relates broadly to. improvements in water treating apparatus, and more particularly to base exchange water softeners.

One of the objects of theinvention is to pro- 5 vide' an assembly ring in association with the apparatus whereby the apparatus may be conveniently installed, dismantled, and operated.

Another object of the invention is to provide a plurality of conveniently located valves whereby the softening, regeneration, and backwashing operations of the apparatus may be readily accomplished without the necessity for complicated and intricate valve structures.

Another object of the invention is to provide l5 a base exchange water softening apparatus which is inexpensive to -p construct and install, and which is efficient in performing its water softening function.

With these and other objects in view, the in- Vention resides in the features o f construction, combinations of elements, and arrangement of parts disclosed in the accompanying drawing, in which- Figure 1 is a side elevational view ofthe apparatus, a portion of the tank being broken away to illustrate parts located interiorly of said tank; and- Figure 2 is an enlarged vertical sectional view of the assembly ring illustrating its construction 80 in detail.

Referring to said drawing, the reference numeral l designates a cylindrical tank supported by a plurality of feet 2, said tank being designed to contain the granular base exchange silicates $5 or zeolites (not shown). A drain pipe 3? is' located adjacent the bottom of the tank and the tank may be drained of water by opening the valve 4. c

The top of the tank has an opening dened by an annular flange 5, to which is attached, as

by means of bolts or machine screws, an assembly ring 6, a gasket 1 being interposed between the flange 5 of the tank opening and the assembly ring 6. As shown in the drawing, the assembly ring 6 is provided with annular anges at its upper and lower edges.

The ring is closed by a removable cover `9 and is maintained closed by a yoke clamp 8 adapted to engage the under side of the upper flange of the ring 6. Pressure is exerted on the cover 9 byfa screw I0 adapted to be rotated by a handle II. A gasket I2 is disposed between the cover 9 and the ring 6 to aord a water tight joint. u An elbow I3 is preferably formed integral with (Cl. 21o-24) the assemblyI ring 'Beat a point in its side wall and has its opposite ends interiorly threaded, the inner end of said elbow receiving the upper end of a tube I4 which is suspended interiorly of the tank at its diametrical center and whose 5 lower end terminates at a spaced distance from the bottom of the tank and accommodates a frusta-conical shaped strainer I5. 'I'he ring 6 at a point diametrically opposite to the elbow I3 is apertured and threaded to 10 receive the inner end of a pipe I6, the outer end of the pipe I6 being connected to a. T I1. Extending downwardly from the T I1 is a pipe I3 leading to a drain, the pipe I3 being equipped with a valve I9. Extending upwardly from the 15 T I1 is a pipe 20 leading to a T 24 in the water service line 2|, -the lpipe 29 being equipped with a valve 22 and a connecting union 23.

Threadedlyl received in the outer end of` ,the

elbow I3 is the inner end of a pipe 25, the outer 20 end of which is connected to a T 26. Extending vertically from the T 26 is a pipe 21 leading to a T 28 in the water service line 2l, the pipe 21 being equipped with a. valve 29 and a connecting union 30. g5

Extending horizontally from the T 26 is a pipe 3I connected to an L 32, which latter is connected to a vertically disposed pipe 33 leading to a T 34 in the water service line 2|, the pipe 33 being equipped with a Valve 31 and a connecting 30 .union 35.

A valve 36 is disposed between the T 34 and the T 28 in the service line 2|.

During the water softening operation, valves Il, I9, 29 and 36 are closed, and valves 22 and 31 35 are open. Thus, as shown by the arrows in 'Figure I of the drawing, untreated water from the service line flows through the pipes 2D and I6 into the ring 6. whence it is precipitated downwardly through the base exchange silicates or 40 zeolites in the treating chamber to the bottom of the tank I; thence ows upwardly through the tube I4, elbow I3, pipes 25, 3I and 33 delivering treated or softened water to the service line 2| supplying the premises where installed. 45

After a period of operation, the treating chainber will accumulate lobjectionable foreign matter or impurities which are removed by a process known in the art as backwashing in which the normal direction of ow of the water through 50 the treating chamber is reversed, and thevwater and objectionable matter conducted to a sewer or drain, In the present apparatus backwashing is accomplished by closing al1 valves with the exception of valves 29 and I9. Thus, water from u the service line 2| will flow only through pipes 21 and 25 into the treating chamber through the tube I4, whence the flow is upwardly through the softening mineral agent and outwardly of the tank l through pipes I6 and I8. The backwashing operation is continued until such time as allundesirable matter has been cleansed from the treating chamber.

Base exchange silicates period of use become ineffectual and regeneration becomes necessary to regenerate the same to restore their base exchange properties. This is ordinarily accomplished by rinsing the silicates or zeolites with salt water.

Regeneration is accomplished in the following manner with the apparatus: All valves, except valve 4, are closed, valve 4 being opened to release the pressure in the treating chamber. The cover 9 is removed and an appropriate quantity of salt introduced in the tank through the ring 6, after which the cover is replaced and again clamped in place. Valve 22 is then opened to permit water to flow through pipes and I6 into the tank, where it dissolves the salt. The salt jwater then passed downwardly over the silicates or zeolites to regenerate' the same, after which it makes its exit throughthe drain 3 into a sewer. The regeneration operation is continued until such time as complete regeneration takes place and the ywater emanating from the drain pipe 3 is free of salt. If desired, valve,

36 may be kept open during regeneration so as to keep a supply of untreated water in the line servicing the premises.

It will be noted that the entirel system is connected to the assembly ring so that the assembling and installation is simple. Moreover the unions 35, 30 and 23 are in alignment and dismantling or removal of the apparatus requires only that these three conveniently located unions be disconnected. All of the valves are readily and zeolites after av "to the opening, the end portions-of the elbow being threaded and one end portion thereof being in register with a second opening providedv therefor in the side of the member, a tube in the tank threaded into engagement with the other end portion of the elbow, a pipe threadedly connected to the first named threaded opening vof the member, a pipe threadedly connected to the first named end portion of the elbow, a closure seated on the upper flange of the member, and means to removably connect the closure to the said upper flange of the member.

2. In a Water treating apparatus, a tank having an opening, an open-centered one-piece member, means to secure the member to the tank with its open center alined with the tank opening, said member having an opening extending through a side thereof, a pipe threaded into engagement with the said opening of the member, an elbow integral With and merging into the member and having one end in register with a second opening provided therefor in the member and spaced from the first opening of the member, a pipe threaded intoI engagement with said last named opening, a pipe in the tank threadedly engaged in the other end of the elbow, a cover for the member, and means to secure the cover in position.
